WE HAVE TO AVOID

tire muscles.
      It is impossible  to build most effective elastic muscles with more than 3 repetitions.       Remaining energy should be used by adding the next weighted belt. If we pushing up the 50 lb weighted belt  and feel, we could do more than 3 times, instead to do 4 times we have to add the 3- 5 lb weighted belt. And again, when enough energy is built to produce 4 repetitions, we have to add next weight belt and so on.

WOMEN NATURALLY

have elastic muscles.
          If a men have to work hard to build most effective elastic or flexible  muscles, to women they have been given in their birth. This is why, statistically, women  less suffer with heart troubles and live longer.
         Despite involvement of some modern women in use to be "man" sports (box, soccer, hockey, power lifting and some others), none  of them built hard muscles.
